Description
Summary:Effects of Fe deficiency and pCO 2 increase on (A) chlorophyll a (Chl a ), (B) photosynthetic yields (F v /F m ), (C) functional absorption cross sections (σ PSII ) and (D) time constants (τ) in the four treatments of P . subcurvata ( +Fe 190 , Control 190 , +Fe 290 and Control 290 ) at the end of the experiment. The values represent the means ± SD (n = 3). Different letters indicate significant differences between treatments (p < 0.05).
